Rohingya insurgents attacked several police posts and an army base in Myanmar on Aug. 25. The ensuing clashes and a military counter-offensive has killed at least 400 people and triggered the exodus of more than 160,000 people to neighbouring Bangladesh.

Malaysia, hundreds of km (miles) to the south on the Andaman Sea, is likely to see more boat people from Myanmar in coming weeks and months because of the renewed violence, said Datuk Zulkifli Abu Bakar, the director general of Malaysia Maritime Enforcement Agency. Malaysia is already home to over 100,000 Rohingya refugees.

“We are supposed to provide basic necessities for them to continue their journey and push them away. But at the end of the day, because of humanitarian reasons, we will not be able to do that,” Zulkifli told Reuters, adding that no fresh refugees had been seen yet.

Malaysia, a Muslim-majority nation, will likely house the Rohingya refugees in immigration detention centres, where foreigners without documents are typically held, he said.

Malaysia, which has not signed the U.N. Refugee Convention, treats refugees as illegal migrants.

Thailand has also said it is preparing to receive people fleeing the fighting in Myanmar

There are about 59,000 Rohingya refugees registered with the United Nations High Commissioner for Refugees (UNHCR) in Malaysia although unofficial numbers are almost double that.

In 2015, mass graves were exhumed at jungle camps on the border between Thailand and Malaysia that were thought to be mainly Rohingya victims of human traffickers. – Reuters
